In the review for e83842b80b it was
pointed out that keypairs should be added to the eager load list for
get_metadata_for_instance_id. Due to a lack of a proper context in a
thread in the ironic driver, this actually totally broke ironic.
The context problem is being fixed elsewhere, but this should be
eager-loaded to minimize DB queries anyway.
